Review on 🔌 PrimoFlex Advanced LRT Soft Flexible Tubing - 3/8in. ID x 5/8in. OD, 10 feet - Onyx Black: Durable and Versatile Tubing for Various Applications by Kendriece Figueroa

I am sure this is an excellent whistle but it was very difficult for me to work with. I couldn't fit it into the XSPC barb without a hair dryer and it's not possible to tighten the fasteners on the barb to secure it. My fingers are currently blistered and calloused from trying to work with this whistle and I cannot justify brand recognition with the difficulty of working with this material.
